Lt. Gov. Anthony Brown and Larry Hogan have been going head-to-head in the race for Maryland governor for four months, but the race is now getting some national attention because it might be too close to call.

Within in the past three days, two respected national non-partisan political tracking groups, the Cook Political Report and Real Clear Politics, switched the race from "leans Democratic" to a "toss-up."

A few polls have Hogan, a Republican, behind by a couple of points, while a few others have him ahead. The real estate executive is fresh off a blistering weekend visit from New Jersey Gov. Chris Christie, and on Monday while pushing his anti-tax message, he was working for every last vote with confidence.

"The national media and the pundits all around the country who had ignored us for months and thought Maryland wasn't even on the radar screen are now saying this is going to be the biggest upset victory in the entire country," Hogan said while on the campaign trail.

Still, most polls have shown Brown in the lead. The latest had him up by 13 points.

"This election is not about the past and where we've been. This election is about the future and what's next and the opportunities we create for more and more Marylanders," Brown said Monday at a rally that included first lady Michelle Obama.

The rallies are meant to pump up voter turnout, but there was a different strategy Monday night from the non-partisan community organizing group called BUILD. Volunteers by the busload canvassed Baltimore neighborhoods to make sure the city repairs its apparently declining political prowess.

"In the last two elections, our voting percentages have been down," said BUILD spokeswoman Glenna Huber. "I think if you don't vote, then your voice is not heard, and people may be feeling as if Baltimore is not significant in Maryland politics."

But it's been a different story in Baltimore County, where turnout has been about 60 percent. The county, which has moderate Democrats and many Republicans, could play a role in who wins the race Tuesday night.
